To all' whom 'it may concern:

lfle it knownthat I, CHARLES S. LABorisn, {atmen-ot the United States, and resident ot' Bright-*wood Park, YVashingtfon, in the District of Columbia, have invented certain nev7 and useful improvements in Type-Triting Machines, of Which the following is aV specifications My invention relates more particularly to tahulntingdevices for typewriting machines andfit consists in certain parts and combinations which will he particularly described herein and set forth in the appended claims.l

My invention is illustrated in the accompartying,Y drawings inl which,

Figure 1 is ay 'front elevation ot so much of a typewriter as is necessary to illustrate my improvements, the key hoard being shown in vertical section on the line t1-m' of Fig. Fig. 2' is a vertical longitudinal section through the machine; Fig. 3 is a perspective view of the carriage 'feed device. Fig. L illustrates a` detail. Fig. 5 is a horizontal section, partly broken away, through the ke)T hoard. Fig. t3' is a detail end elevation, a shatbeing shown iu section. Fig. T is a perspective view ot a frame forming` part ot my device.

My invention is applicable to various iorins of typewriting machines, hut for the purpose of illustration l have shown it as embodied in a Smith Premier typewriter, this being a form ot Writing machines Well known.

The typeWrit-ing machine comprises a main frame 1 upon the upper part of which slides a paper carriage 2 having a cylindrical platen 3. Thetype harseare mounted in circular arrangement about the printing point and are rigidly fastened to oscillating sha-tts 5 having crank arms G connected hy links 'T to crank arms 8 on shafts 9 oscillated in one direction by keys through the medium of cank arms 11 and returned to normal position hy springs 12. The key stems slide in i'raine pieces or guides 13 and have upon their upper ends the usual huttons .1st hearing' characters corresponding; to the characters upon the respective types. A traine 1oar or plate 15 extends across the hack or" the machine' and forms the end support Jfor the several shafts Sl'each of which has near its rear end an eccentric projection 16 in contact with a frame 17 mounted to I have reciprocatory ino-tion upon said plantev l 15, (see Fig. 4l). The construction is such that Whenever any key is depressed' the freine 17 will receive a slight lateral movement and thus oscillate a bell crank lever 18 pivoted to the plate at 19-and pivotally connected to the trame 17 at 20. To the other arm ot' said hell crank is pivoted av link 21 connected to a crank arm 22 fixed' to an oscillating shaft 23 journal-led in av projection from the main frame. Fixedl to the other end of said shaft is a member 211 havinga toe 25 and ay projection or dog 26'. dog` 27 is pivoted to the main frame at 28' and carries a set screw 29, the lower end' of which stands over the-toe 25.

The dog- 2T and the dog or projection 26 together constitute an escapenientl coperating with a rack bar 30 forming part of the carriage. T he said carriage is drawn in a transverse direction by ay spring Which isinclosed in and actuates a` drum a, which is connected to the carriage hy a strap 5. Whenever a key is depressed and the frame 17 isre ciprocated, the shaft 23 is oscillated7 depressing the projection 26 into the path ot' one of the teeth of the ratchet and lifting the dog 27" out of engagement With one of said teeth and letting said dog come into engagement with the next tooth ot the series upon the release of the key.

A bar 31 is pivoted toy the carriage at 32 and is normally held in the position shown in Fig; 2 hy a spring A. projection 34 from the dog 27 stands over this bar so that the liar be raised, the dog 27 will be lifted from engagement With the rack and the carriage he treed from its escapenient mechanism. rlhe har 33 is lifted for this purpose by a release key pivoted to one of the'end traine hars of the carriage at 36 and having a linger piece 535 by which it may' be conL veniently depressed. The machine as thus tar described, is old and Well known in the a rt.

'llo the front ot the paper carriage I at- 100 ,tach a screw threaded rod 37 by means of arms 38 projecting` trom the carriage. Upon this rod l mount a stepped cone 39 having internal screw`thrcads so that it can oe given any position lengthwise of the rod hy turn'- 105 whereby it may he adjusted vertically so es 1rel 2 eoaeie to cooperate With any one of the steps of the cone 39 to stop the carriage in any one of a number of different positions. The steps of the cone have a lateral width equal to the letter space of the machine, that is to say, equal to the distance apart of the teeth of the rack 30. The stop 40 may be adjusted vertically differential distances to cooperate with any one of the steps of the cones by means'of a differential mechanism which Will now be described.

Beneath the key board, and extending from right to left near lthe first rovv of keys, I provide a bar 41 slidably mounted upon rods or screws 42 by means of bearings 43. f The rods 42 are lxodly mounted in the frame of the machine and have springs 44 coiled about them and compressed. between a portion of the frame Work and the bear`- ings 43, thus pressing the bar 41 toward the front of the machine. .The bearings 43 have slots 45 through which entend levers 46 and 47 pivoted u on the respective rods 455. rlhe levers 46 and) 47 are formed with graduated projections 4 8 extending through slots 49 in the bar 41. The bar 41 is provided with a series of projections 5G, one for each of the slots 49. The levers 46 and 47 are provided upon their inner ends With vertically arranged segmental racks 51 and 52 respectively, and are normally held in an el vated position by springs 53 supported ngers 54 depending from the bar 41.V The racks 51 and 52 are adapted to engage a horizontally arranged. elongated pinion 55 but are normally held out of engagement with said pinion by the springs 53. The bar 41 has a vertical projection 567m is 'connected a push key 57 projecting through the iront 'of the key board casing and by which the frame may be pushed against the tension of the springs 44 to its rearward position. The projections 48 and 50 are so arranged that When the frame is thus pushed to its rearward. position each of the projecticuas 48 comes under the crank arm 11 connected with oneyof the keys oi' the first row and the projections also come under said crank arms.

to itsrearward position by'means of the key 57 and one of the keys 10 be then depressed, lsaid key will flfpress the lever 46 or 4 7 through its projection 48 and the downward motion of the key Will be limited by the contact of the arm 11 vvvith vthe projection 50 which thus determines the exact distance the key can be de'ressed, which distance, however, is not su cient to'cause the type to print. The projections 48 and 50 are so .lproportioned' that ,the dilerentkeys give different degrees of motion tothe racks '51 'and 52/jand oscillate the pinion 55 to different extents. A

TheI pinion is journaled atits front end It is obvious that if the frame 4l be movedI in the key board framework and at its rear end in a iframe piece 58 attached to the main frame ot the machine at 59 and to the key board trarne work at 60., The stop 40 is the upper end portion of a slide 61 mounted to have a reciprocatory movement on the frame with a prolongation of said pinion 55. The

slidel is drawn towards its lower position by a spring 59 attached at one end to said slide and at the other end to the trame piece 58. It is obvious that the racks 51 and 52 oscillate the pinion 55 in opposite directions.

When the rack 51 is depressed the pinion 55 is. oscillated to the left, as .shown in the drawings, with the result that the bar 6G elevated and the bar 65 depressed. l/Vhereas if' the rack 52 is depressed the pinion is,

turned to the right and the bar is elevated and the bar 66 depressed. In either event the slide S1 is elevated,` and as before remarked, the different .keys are arranged to elevate the slide different distances.

The bar 4I may be conveniently constructed as shown, of sheet metal in which case the bearings 43 are made by .bending the ends of the metal as shown, and the projec tions 5G are formed by striking up the material from the slots 49 and the projections 5 and 56 may be formed by appropriately shaping the sheet metal and bending the projections as shown moet clearly in Fig. 7.

Upon its opposite edges near the upper end the slide (il. is provided with rack teeth 70 cooperating with pinions 71 jourualed on pins or screws projecting from the main fran/ie of the machine. Integral with said pinions are cams 72 having groei/'ed faces 73 cooperating with a yoke shaped frame or 'bail 7 4 attached at one end to the release key 35 and at the other end pivoted to the carriage. Whenever the slide 6i is elevated the pinions 71 are rotated and the cams 72 depress the yoke 74 and thus-operate the ,release key to release the carriage from its escapement mechanism,

It will be observed that for the purpose of operating my tabulating device I utilize some of the ordinary keys of the machine. Normally the sliding frame 41 is in such a position that it does not interfere With theV yuse of the keys for writing `purposes and the projections 48 and 50 -cannot be struck by the keys; but when the key 57 is pushed in,

' the tabulating device is brought into position to be operated by certain of the Writing keys. In the present instance I have shown bestruck by the longest or outermoststepI '-75 ofthe cone 39. rlhe key 77 elevates the sonore y et,

ten of the keys of the first row as coper` ating with the tabulating device. The bnttons of these keys may be provided With characters such as l l 100 &c., up to hundreds of millions, to indicate to which denominational position each key is adapted to bring the carriage. I prefer, however, that the character keys used for this purpose be the numeral keys of the typewriter, the several buttons le of which bear (C 0 77, Cy l 77, 16277, 3 77 i 4: 77, H 5 77, 6 7, 8 and 9, corresponding to the character which each key is adapted to print. Then the frame 4l is pushed under the keyh, these-characters lindicate the dnoininational positions to Wliich the several keys are adapted to bring the carriage, the' 0 key being for the decimal point, the l key for units place,'the 2 key for tens place, etc. Y

The parts are so graduated that the key 7 6 elevates the stop 40 the shortest, distance of any key, thus bringing it into position to stop 40 a little higher bringing it into the 'path ofthe step 78 of the cone 39, and so on across the machine, each succeedingkey correspondingl to a successively lower step on the cone.

In the' operation of my device,.the largest step 75'of the cone 39 is adjusted according to the carriage scale V 79 to -the position in which: it is desired to Write the decimal point. II", then, it is desired to brineT the carriage to thisoosition, the key 57 is pushed in and the key" iG depressed until it is stopped by its 'projection 50. This turns the pinion -55 to a slight extent to the left thus elevating the slides 66 and 61 and the stop 40. This motion of the slide 61 turns the cams 72, depressing the yoke 7e and release key 35, thereby relea sing the ca1'riage,ovhereupon the carriage drawn to the left by the strap 'and stopped by contact of the step 75avith the stop 40. It the tirst gnre of the number to be written is in some denomination. such as units. tens, etc.. the operation is the same except. that the key corresponding with that denomination is depressed instead of the key 76;

The 'sca-le 79 is the ordinary carriage scale of the machine and is read by reference to u indexv finger 80. It will be observed that my tabnlator is arranged in front of the machine where it is convenient for inanipn` i lation by the operator and that the stop cone 39 may be readily adjusted on its rod by reference to the said carriage scale 79. which lies behind said cone.

lVhile I have described the preferred embodiment ofniy invention. I am aware that many modifications may be made without departing from the spirit of my invention. Forexample, it is not absolutely essential that the conical nut 39 should be circular in cross-section, although in the present case I prefer the form shown. So far'as I am aware, it is new to provide a denominational stop device in the form of a threaded nut with any form of stepped faces at ditl'erent distances from the axis of the nut.

It has been common heretofore to locate the denominational stops either on the carriage or on the frame of the machine and to locate the cooperating tabnlating stop or stops accordingly. I do not, therefore, wish to be understood in all cases to be confined as to the location of the denominational and tabnlating stops. i

Some or' the features set -forth in the present application are also shown and are more broadlyl claimed in my prior applications, Serial No. l2,670, tiled*v January 9th, 1901; Serial No. 5f-3,670, .tiled March 30th, 1901 and Serial No. 127,412; filed (lctober 15th, 1902. 'l
